TRUCK.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed September 12, 1913. Serial No. 789,488.

To all 1071 one it may concern:

Be it known that I, HERMAN H. JUERGENS,

a citizen of theUnited States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Trucks, of which the following is a specification.

This invention has relation to trucks adapted to be used for moving baggage and eXpress matter and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a truck of the character indicated having its parts so arranged that the platform of the truck may be readily raised or lowered.

l/Vith the above object in view the truck comprises a platform having brackets pivotally connected with the opposite end portions thereof. The said brackets being pro- Stops are mounted at the under side of the platform in the path of movement of the shoulders and are adapted to be engaged by the same when the said brackets are directly under the platform. Ground wheels are journaled to the brackets. A shaft is ournaled for rotation under the intermediate portion of the platform and carries a winding drum about which is wound two cables. Means is provided for turning the shaft and the cables are trained over suitable pulleys and connected with the brackets so that as the shaft is rotated the brackets are swung simultaneously away from each other or toward each other. As the brackets move away from each other the platform lowers and as the brackets move toward each other the platform is elevated.

In the accompanying drawing :-Figure 1 is a side elevation of the truck. Fig. 2 is a bottom plan view of the same. Fig. 3 is an end elevation of the same. Fig. 4 is a transverse sectional view of the same cut on the line of Fig. 2. Fig. 5 is-a plan view of a drum and adjacent parts used upon the truck.

The truck comprises a platform 1 to the end portions of which are pivotally attached brackets 2. The brackets 2 are provided at their inner sides with shoulders 3 which are adapted to encounter stops or legs 4 attached to the platform when the said brackets are completely under the platform. Wheels 5 are journaled to the brackets and the brackets 2 are provided at their inner sides with cable guides 6.

A shaft 7 is ournaled for rotation under the intermediate portion of the platform 1 and a drum 8 is mounted upon the said shaft. Cables 9 and 10 are wound about the drum and are so arranged that as one end portion of the cable is wound upon the drum theother end portion thereof unwinds from the same and vice versa. One run of each of the cables 9 and 10 extend directly fromthe drum 8 to one of the brackets 2 and the other run of the said cables is trained over a pulley 11 journaled at the end portion of the platform 1 and then extends down and is secured to the lower portion of the adjacent bracket 2. A worm wheel 20 is fixed to the shaft 7 and a worm 18 mounted on a shaft 14 engages the said worm wheel. The shaft 14 is j ournaled for rotation under the platform 1 and extends beyond one end thereof and a crank handle 15 may be applied to the projecting end portion of the said shaft. Therefore it will be seen that by turning the shaft 7 and drum 8 the brackets 2 may be swung from under the platform 1 whereby the said platform may be lowered. After the platform has been lowered it may be loaded with articles and when it is desired to transfer the articles from the truck to a car or other vehicle the shaft 7 and drum 8 may be turned whereby the brackets 2 are drawn back under theplatform 1 and the said platform is elevated. Thus the articles upon the platform are raised and may be readily shifted from the platform to the floor of the car.

Having described the invention what is claimed is 1. A truck comprising a platform, brackets pivoted to the platform, wheels journaled to the brackets, a drum journaled upon the platform, a cable connected at both of its ends with each bracket and the intermediate portions of all of the cables arranged to wind upon the drum.

2. A truck comprising a platform, brackets pivoted to the platform, cable guides carried by the brackets, Wheels journaled to the In testimony whereof I afiiX my signature brackets, a drum journaled for rotation unin presence of tWo Witnesses.

der the )latform, a cable connected at both *1 of its en ds with each bracket and the inter- I HERMAN JUERGENb mediate portions of all of the cables ar- Witnesses:

ranged to Wind upon the drum, said cables NAT D. HULL,

engaging said cable guides. GLENN A. SMILEY.
